Description

Broadcom ACHS-712x Series: Fully Integrated Hall Effect Linear Current Sensor ICs

The Broadcom ACHS-7121/7122/7123 product series represents a fully integrated, Hall Effect-based isolated linear current sensor family. Designed for accurate AC or DC current sensing, these devices are ideal for industrial, commercial, and communications systems. Each sensor features a precise, low-offset, linear Hall circuit integrated with a low-resistance copper conduction path (0.7 m typical) for efficient current sampling with minimal power loss. The output voltage is directly proportional to the applied current, offering a ratiometric output from the supply voltage. With a compact SO-8 package, these sensors meet worldwide regulatory safety standards and provide robust isolation (3 kVRMS).
